FRAME FOR PHONOGRAPH -MOTORS.

- Application filed April 9,

J '0 (HZ 107mm it may concern I Be it known that I, GEORGE T. CHERING-TON, a citizen of the United States, residing at Waukegan, countyofLake, and State of Illinois, have invented certainnew and usefulImprovement in Frames for Phonograph-Motors, of which the following is aspecification.

y invention relates to that class of phonograph motors, in which themotive power is furnished by the springs, and has for its object toprovide a frame which will be so constructed that practically all of theoperating mechanism-is inclosed in a chamber, which is provided with anoil reservoir so that the oil by means of capillary attraction willtravel to every part of the operating mechanism.

It is desirable in devices of this character to provide a constructionwhich will enable the manufacturer to use as many driving springs as hedesires. IVith the frames-for this purpose with which I am familiar, itrequires a different frame for every change in the number of springs.

My invention has for its object to provide a construction in which onlya single part needs to be changed in order to change the number ofsprings employed and this part will not in any way interfere with any ofthe operative mechanism.

My means of accomplishing the foregoing objects may be more readilyunderstood by aving reference to the accompanying drawing, which ishereunto annexed and is a part of this specification, in which:

Figure 1 is a top or plan view of my in1- proved frame.

Fig. 2 is a fragmentary detail view taken on the line 2 2 in Fig. 1.

Similar reference numerals refer to similar partsthroughout the entiredescription.

As shown in the drawings, the frame comprises a rectangular portion 1,one side 2, Of which is open and is fitted with a detachable plate 3. Atthe lower part of this opening is cast or formed a wall 4, whichpartially closes the opening and forms an oil reservoir or chamber inthe bottom part of the rectangular frame. The plate 3, can be drawntightly against the walls of the cham her by means of screws 5, or anyother suitable and convenient means of fastening. If desired, a suitablegasket can be mounted intermediate the wall and the plate, making it oiltight. A plurality of lugs depend Specification of Letters Patent.

,with a flange, which Patented Sept. 27', 1921. 1920, Serial No.372,567.

downwardly from the bottom part of the frame. s shown, they are two innumber and are indicated by the reference numerals 7 and 8.- These lugsare provided with openings, through which extend and in which is mounteda shaft 9, which may be secured to one of the legs by means-of a pin 10,or in any other suitable or convenient fashion. [This shaft 9, extendslaterally from the casing 1, and carries at its outer end an outboardbearing 11, which is detachably secured to the shaft 9, by means of apin 12. This bearing contains an outwardly extending arm 13, in whichmay be mounted the spring shaft 14.

It will be apparent from the foregoing description, and from aninspection of the drawings, that *I have shown two driving springs, butif a larger number was required, all that would be necessary to do wouldbe to remove the pins 10 and 12, take out the shaft 9, and insert one ofthe desired length when the outboard bearing 11, can be fitted upon theend of the new shaft, and this is the only change that will need to bemade, all of the operating mechanism remaining in the same position thatit is in when two or even one spring is employed. I provide an apron orguard for the intermediate gear, and to form bearings for the shaftwhich carries the said gear. This apron 15, extends laterally from thecasing, and is semi cylindrical in shape, and is provided closes theouter end of the semi cylindrical apron, and in which is mounted abearing for the intermediate shaft, the wall of the casing forming theother bearing.

It will be apparent from the drawings and the description that themovement of the mechanism in the chamber will cause the oil to bethoroughly distributed and it will, as a consequence, travel bycapillary action over the entire interior wall of the structure and upand into the bearings, particularly of the turn table shaft and governorcontrol stem, as well as reaching and thoroughly oiling all of the othershafts, which are journaled in the casing, so that by the use of myimproved frame, I not only secure improved oiling, but by inclosing theoperating parts reduce the noise to a minimum.

I also provide a motor to which can be added as many springs as aredesired without changing the operating mechanism in the slightestdegree. In some cases it may be found desirable to employ an electricmotor in the place of spring motors, in which case, it can be'mounted onthe spring shaft, and a pulley can be mounted on the intermediate shaftin the place of the collar 18, which when used with a spring motor holdsthe shaft in position. 4

Having described my invention what I regard as new, and desire to secureby Letters Patent is:

1. A frame for phonographs, comprising a rectangular casing, having achamber therein, open on one side, a wall partially closing said side, adetachable plate covering both said wall and said open side, a pluralityof downwardly depending lugs, having openings therethrough, a shaftmounted therein, an outboard bearing mounted on said shaft, a semicylindrical apron extending laterally from said casing terminating in aflange, and a bearing in said flange.

2. A frame for phonographs, comprising a rectangular casing, having achamber therein, open on one side, a wall partially closing said side, adetachable plate covering both said wall and said open side, a pluralityof downwardly depending lugs, having openings therethrough, a shaftdetachably mounted therein, an outboard bearing detachably secured tosaid shaft, a semi cylindrical apron extending laterally from saidcasing terminating in a flange, and a bearing in said flange.

3. A frame for phonographs, comprising a rectangular caslng, having achamber therein, open on one side, a wall partially closing said side, adetachable plate covering both said wall and said open side, a pluralityof downwardly depending lugs, having openings therethrough, adjustablemeans carried by the lugs, and an outboard bearing detachably securedthereto.

4;. A frame for phonographs, comprising a rectangular casing, the lowerrear corner of which is indented, having a chamber therein, open on oneside, a wall partially closing said side, a detachable plate coveringboth said wall and said open side, a plurality of downwardly dependinglugs, having openings therethrough, a shaft mounted therein, an outboardbearing mounted on said shaft, a semi cylindrical apron extendinglaterally from said casing, terminating in a flange, and a bearing insaid flange.

In testimony whereof, I have signed the foregoing specification.
